COMBINED PUMP HEAD-AN D POWER HEAD. Application filed January 12, 1925. Serial No. 1,861.

This invention relates to improvements pump head but extended to fit within the in combined pump heads and power heads support as in Figure 1. for use in connection with water pumps, Fi ure 4 is a plan view of what is shown particularly of the deep well type adapted in Figure 3 except that the power casing 5 for domestic and other uses. is in horizontal section. 60

Figure 2 is a horizontal section of the casshown in F 1gure.3. In either case t a pump ing and plan view of the pump head and its head constitutes a hollow shell into which 9 parts, as also a plan of the two-member supthe water is dehvered by the pumpm port. mechanism and thence discharged throng Figure 3 is a like view to Figure 1 showany convement pipe hue attached to e ing a modified form in which the drop head by means of the screw-threaded neck; is placed within the support instead o ,e 12. This pump head may be made of the port the pump head and form shown in Fi ure 1 with the extension beclamped by the mem- 'bers of the support and to rest upon the 9 to'fit within an supportas indicated at 4; or the pump head may made to rest upon the support as indicated at 4 in Figure 3 and the drop pipe 13 be fitted within the support and be clampedand held thereby.

The pump head may further be provided with a cap 14 into which is screwed anupper cylinder 15 within which operates the upper section 16 of the pump rod equipped with a piston or plunger 17, as shown in Figure 1; or instead, may be equipped with a conventional stuiiihg box as shown at 18 in Figure?) adapted to make a water-tight b joint between the pump head and the piston or pump rod 16* as also shown in that figure.

- p The drop pipe, whether connected to the extension 9 of the pump head 10 as in Figure 1, or'connected to the body of the pump head as shown in Figure 3, is conventional lIl character and 1s adapted to extend down into a well and to support the lower cylinder of the pump.

It will now be seen that I have provided a twp-part pump head support in combination with a power head casing, and that one member of this support may be. readily removed for mounting on and Within the supdrop pipe and be likewise readily reconnected with the other member so as to complete the support and effect a clamping action by which the pump head and drop pipe are securely held and accurately positioned in the proper place to bringthe piston -or pump rod into t e required vertical plane to agree with the plane in which will travel the actuating part of the operating mechanism, so that this act-uating' part will not tend to deflect the. rod from its line of movement. It is a material matter to efict the automatic correct positioning of the piston or ump rod with respect to .the power mec anism within the casing by the mere act of assembling the pump head and drop pipe with the support.

It is a further material matter 'to be able to readily machine the upper surface and the interior of the support so as to insure this accurate positioning ofthe parts when assembled. These pumps are made in large uantities at the works of my assignee, and t 1e interest of the public requires that they be produced economically so that they may be sold at reasonable prices; and the further interest of the public requires that the power head and pump head may be readily assembled at the place of use in suchwise that the piston or pump rod will be properly positioned, as before stated, and in suchwise also that the pump head and'drop pipe shall e firmly maintained in position when once assembled so that the structure will continue to operate with facility and efficiency.

The leading characteristic of this invention resides in the combined two-part ,support, one part connected with the power head casing and the two parts detachably connected together and forming, when assembled, a support and clamping device by which the pump head and tioned and secured.

It will be understood that I'desire to comprehend within my invention such modifidrop pipe are posiv cations as may benecessary to adapt it to circular opening, and a ump head having an extension with a s'houl er at the juncture of a.

the head and extension, such shoulder bein adapted to rest upon the support and such extension to fit within said recesses.

In testimony whereof, I aflix my signature.
